PAPER-BOX COVERING AND TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent- No. 253,711, dated February 14,1882.

' Application filed November 29, 1881. ma i) To all whom it may concern Be it known that I, HORACE INMAN, of All]- sterdam, in the county of Montgomery, and in the State of New York, have invented certain new and useful Improvements in Paper-Box Covering and Trimming Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, reference being had to the accompanyingdrawings, and to the letters of reference marked thereon, making a part of this specification.

This invention relates to that class of machines employed for automatically covering boxes with an outer coating or surface of paper, cloth, &c.; and it has for its object, first, to provide mechanical means for supporting, pasting, and conducting the material used for covering to the boxes, and, secondly, in providing means for sustaining and revolving the boxes while undergoing the process of covering. These-objects I attain by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my apparatus; Fig. 2, an end elevation, looking toward the end of the machine carrying the reel on which the paper, cloth, or other covering material is wound. Fig. 3 is a plan or top view of the ma chine. Fig. 4 is a detail perspective view of the standards which sustain a paste or glue drip pan or tank, the transverse bar for supportingthe paper, and the guiding points or fingers. Fig. 5 is a perspective view of a box, showing the covering and trimming applied thereto; and Fig. 6, a detail perspective view of the carriage to which the form is secured and the track on which said carriage travels.

The letter A indicates a pair of legs or standards, which are made in any convenient or desirable form, and of any material found most suitable for the purpose, preferably of cast-iron, and which are connected or otherwise braced together about midway their height by a rod or bar, A, theirlower ends being firmly secured to the floor. The upper extremities of these legs or standards are bifurcated or divided respectively into two vertical extensions, B. These extensions are provided with suitable apertures and set-screws for the reception and retention of the bars or ways G, one end of each of thelatter being also bored out, as indicated at C, for the purpose of receiving the journals of a reel, D. This reel is constructed of a series of disks strung on a shaft a short distance apart, forming deep grooves or passes, in which the several strips ofcovering material or paper are wound.

The letter E indicates a paste tank or vessel having a double bottom, for a purpose hereinafter named, made of any suitable material, resting at each of its sides on the said bars 0. Immediately above 'said tank is journaled a paste delivering roller, F, adapted to come down a short distance within the said tank and engage the glue or paste therein, for a pur-- pose hcreinafter more fully set forth. At one end, on the upper side of this tank E, is suitably journaled a cross-shaft, G, which is provided wiih a link, H. between which andthe said bar the paper is adapted to travel, the object of which is to remove from the paper all surplus glue or paste, at the same time speadin g and leaving a sufiicient quantity for the purpose intended; About midway the said bars 0, and fitting smoothly thereon, is a pair of standards, I 1, connected at their lower extremity by a cross-rod, which serves to support a tank or pan, J, which catches any paste that may be removed or scraped from the paper during its passage between said standards. At a point above the bars 0 0 another crossshaft, K, is journaled to these standards, having alink, it, projecting from each side thereof, between the lower of which links and the shaft K the two outer strips of paper (or those known as trimmings) are adapted to pass, while between this shat't'and the upper link the covering proper travels. Near the top of these standards I I is a further cross-shaft, L, having strung thereon a series of heads or blocks, M M, the two inner. of which carrydcpending fingers or guides N N, which embrace the edges of the covering material, and-serve to guide the same over the said cross-shaft K, the lat ter being intended to separate the covering material from the side strips or trimming. The two outer heads or blocks are also provided with depending lingers or guides n it, having horizontalcxtensions which fit; under the outer strips or trimming, for the purpose of guiding by means of the paste or glue with which the lower side of the covering is coated.

The letter P indicates another supporting bar or rod, located between upper extensions of one'ofthe -legs,-which, in connection with the rod p, supports the covering and trimming, which have now become united, as they pass between the guides S S, adjustably journaled to the bars O, the latter having set screws T T for retainingthegnides in proper place.

The outside of the legsis provided with a track or way, U U, upon which is adapted to reciprocate a carriage, V. The letter W indicates ascrew-threaded ing, and the letter B .a thumb-bolt, the latter being suitably swived to engage the said lug, by which the said carriage is given a positive transverse motion and brought in such position as to bring the form D in line with the course of the covering. This form is secured to a transverse shaft, E,

journaled in the carriage before mentioned, and

is rotated by means ofa spur-wheel, F, mounted onsaid shaft and meshing with a worm, G, which also has its hearings in the said carriage. The letter H indicates a grooved wheel mounted rigidly on the shaft of this worm, which receives a rotary motion by meansof belt passing over the same and connecting with a suitable driving mechanism, 1, located in close proximity to the machine, and provided with such auxiliary appliances as to render it completely under the control of the operator, permitting him to start and stop the said form at will.

The operationof my machine may be readily understood by the following description in connection with the foregoing: The reel D being supplied with "the covering and trimming material, (usually paper,) the free ends thereof are passed over the paste-roller F, and through the space between the shaft G and the link H, by which shaft and link the paste is properly spread. The coveringis then passed between the shaft K and link It, and the trimming below said shaft, and over the lower link,k, after which they unite at the cross-bar 0, having been caused to lap each other by means of the fingers n n pressing against the outer edges of the said strips of trimming, and thus continue on and over the supports P and p and between the final guides S S until the free end is attached or stuck to the box to be covered. The operator then rotates the form D, thus revolving the box and permitting ofa continuous wind of the covering around the box, that part It will be noticed that during the passage of the covering through the machine any surplus paste which may happen to adhere thereto, after having been applied by the paste-roller F, will be removed by the shaft K and linksk, and caught by pan J.

The paste-tank is' provided with a double bottom, 0 e, the space between which is charged with steam or other heating agent to prevent congealing of the paste.

The tension of the covering material and trimming is regulated by changing the relative position of the paste-roller F, standards I Land rod 0, each of which is adapted to slide independently of the other on the bars 0 '0, their weight being such as to retain them in any fixed position without the aid of any further fastening. The covering and trimming covering and trimming strips, substantially as set forth.

2. In a machine for covering boxes, the supporting-frame, in combination with the pastetank carryin ga paste-roller, the standards with their guiding and supporting devices, and the cross-bar for uniting the covering and trimming, the said tank, standards, and uniting cross bnr being adapted to slide on the supporting-bars, whereby their relative distance is changed and a proper tension of the covering and described.-

3. In a machine for covering boxes, the combination, with the devices, substantially as described,for feeding, pasting, guiding, supporting, and uniting the covering material, of a lateral adjustable carriage carrying a revolving form, and provided with mechanism for automatically rotating the same, substantially as shown and described.

4. In a machine for covering boxes of the character herein described, adapted to manipulate a-plurality of covering and trimming strips of paper, 850., the combination of the standards I I, shaft K, having link k, and shaft L, with beads M M and fingers or guides N n for guiding and lapping thestrips, as shown and described.

In testimony'whereof I affix my signature, in presence of two witnesses, this 17th day of No vember, 1881.
